I hesitate to mention the cars I leased out for beet juice that were last contained sodium hydroxide, not clean. We don't buy beet derived sugar at our house.
Another question: in the steam era were beets crushed and the juice sent to another location for final processing? Always looking for a tank car connection for layout industries.
Sugar beets were partially steam cooked and shredded, and the pulp was the source of sugar. (Done all at one plant.) I would think that "beet juice" would be a vegetable juice, not from sugar beets at all.
